## 타입 정의

물음표(?)는 선택 항목이고 readonly는 직접 변경하지 않는 값입니다. 유니온(|)은 허용된 형태 중 하나를 뜻합니다. 함수는 해당 시점에 Grid가 호출할 콜백입니다.

```typescript
export type GridChartEvent =
  | (GridChartEventSpine & {
    readonly type: 'created';
    readonly chartType: SyChartConcreteType;
    readonly projection: GridChartProjectionKind;
    readonly source: GridChartModelSource;
  })
  | (GridChartEventSpine & {
    readonly type: 'rangeChanged';
    readonly source: GridChartModelSource;
    readonly previousSource: GridChartModelSource;
  })
  | (GridChartEventSpine & {
    readonly type: 'optionsChanged';
    readonly options: GridChartOptions;
    readonly changedKeys: readonly GridChartOptionKey[];
  })
  | (GridChartEventSpine & {
    readonly type: 'destroyed';
    readonly cause: GridChartDestroyCause;
  });
```
